COMBINED PIPEv AND NUT WRENCHi Application led September 21, 1922.Serial No. 589,523.-

1o all whom t may concern i Be it kno-wn that I, GEORGE F onToN, acitizen' of the United States of America, residing at Detroit, in thecounty of Wayne and State of Michigan, have invented cer tain new anduseful Improvements in a Combined Pipe and Nut Wrench, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

One of the objects of my invention is to provide a combined pipe and nutwrench, wherein simple and effective means is ernployed, in a manner ashereinafter set forth, for rendering the pipe gripping action of thewrench temporarily inactive so that the wrench may be used for grippingand rotating a nut or other object having facets or flat surfaces thatmay be engaged by the wrench. j

Another object of this invention is to provide a wrench of the abovetype having a pivoted spring'- pressed shank and gripping jaw which maybe tilted topermit of the jaw being easily placed in engagement with thepipe or other object having acurvilinear surface, and provision is madefor adjusting the shank with a stop to prevent an eXtreme adjustmentwhich would release the shankv relative to the wrench.

A further object of this invention is toprovide a wrench of the abovetype wherein all the parts are compactly assembled and well protected topermit of the wrench being roughly handled without any 'danger of partsthereof being broken.- The wrench is also comparatively light in weight,without sacrificing strength, and the construction entering into thewrench will be hereinafter specifically described l and then claimed.

Referring to the drawing,

Figure 1 is a side elevation of a portion of the wrench, partly brokenaway and partly in longitudinal section;

Fig. 2 is a longitudinal sectional view of the wrench taken on the lineII-II of Fig. 1;

Fig. 3 is a cross sectional view of the wrench taken on the line III-III of Fig. 1, and

Fig. 4 is a similar line IV-IV of Fig. 1.

In the drawing the reference numeral 1 view taken on the adjacent therivet 7.

denotes a handle bar having its outer endv provided with a head 2 andmounted on said head and extending therein is a ser.- rated jaw 3 whichmaybe held byy a rivet 4 or .other fastening means.

5 denotes a strap, oblong in cross section, said strap having'aperturedears V6k plvotally connected to the sides of the head 2 by rivets7 orotherpivotal means extending transversely `of said head which is outaway, as at 8, Vto provide clearance for the ears 6. n 1 j `9 denotes ashank rectangular in crosss'ection land slidable in the strap 5, saidshank having a Xed or integral serrated jaw 10 confronting the Ijaw 8and adapted to cooperate therewith in gripping a pipe, nut or the like.Opposed walls of the shank 9 are threaded, as at 11, and engaging saidthreads is a' cylindrical interiorly screwthreaded nut 12 set in atransverse slot 13 provided therefor in the strap 5, adjacent the innerend of said strap.

14: denotes'a transverse partition carried by the inner end of the strap5 and this partition engages the inner end of the nut 12, while theouter end of said nut abuts the strap 5 and a spring pressed abutment 15set in said strap, between .the handle bar 1 and the shank 9. Theabutment 15 is engaged by a bowed auxiliary spring 16 and the partition14.- is engaged by a bowed main spring 17, said spring having endsthereof mounted in a transverse slot or kerf 1S provided therefor in thehead 2 The expansive force of the springs 16 and 17 holds the inner endof the strap 5 normally away from the handle bar 1, so that the jaw 10will be in proximity to the jaw 8, but may be sprung outwardly from saidjaw when placing the wrench in engagement with a pipe or other object.

19 denotes a channel shape latch slidable on the inner ledge of thehandle :bar 1, said latch being retained in engagement with the handlebar by a flat member 20 mounted on the inner' edge of the handle bar 1.The latch 19 is adapted to be shifted into recesses 21 provided thereforin the Finner end of the strap 5 and when said latch engages the strapitis held stationary so that the shank 9 will not tilt when being usedto engage a nut. Making the strap 5 non-tiltable does not spring orresilient yversely of the shank' 9 'end and when the interfere withadjustment'of the shank the nut 12 in the strap 5. s

22 denotes a stop pin extending transadjaoent its innerv shank 9 isdistended by adjusting/the nut-12, the vstop vlpin 22 is adapted toenterthe nut-12 y inner end of the strap"`"5;' the location oft the stoppin12 being such. that the inner end l of' 'the'v shank engagement withthe' mit thereby? i y By making lthe 9. remains j in `threaded 12 ,to beadjusted l' yabutment 15' detachable v relative to thev'handle`fb-ar"1,'v easy ac'cess that the "strnctural elements are susceptiblebe 'freely rotated in may be had tothe" springs 16 yand 17 and Nsaid@abutment being "interposed between the head2 and thel nut 12 the' nnt12ea'nnot'bind*againstthe'strap 5 and can l the: slot k1310i said Snap.l A l I I One embodiment of my inventionvhas been illustrated', but itis to be understood and engage the to snehI changes as `fall.
